[英]How to resolve this Laravel issue - The “/tmp/phpY14gRo” file does not exist or is not readable?
I need to create PDF's thumbnail every time it gets loaded via POST method.每次通过 POST 方法加载 PDF 时,我都需要创建它的缩略图。 Once I upload the file inside Controller , it runs getThumb function that uses Imagick to create thumbnail.
一旦我将文件上传到Controller中,它就会运行getThumb function ,它使用Imagick创建缩略图。 The problem is that everytime I do that, this request breaks and shows this error - The "/tmp/phpY14gRo" file does not exist or is not readable.
问题是每次我这样做时,此请求都会中断并显示此错误- “/tmp/phpY14gRo”文件不存在或不可读。 .

Imagick is properly installed. Imagick 已正确安装。 I use php-7.2-apache docker image.
我使用php-7.2-apache docker 图像。
But if I run shell_excec script that does absolutely the same thing, it works!但是,如果我运行完全相同的shell_excec脚本,它就可以工作! That eliminates all suspicions of the wrong dependency installation
这消除了对错误依赖项安装的所有怀疑
Here's the function from my controller:这是我的 controller 中的 function:
public function createThumb($source, $target, $size = 256, $page = 1)
{
if (file_exists($source) && !is_dir($source)): // source path must be available and not be a directory
if (mime_content_type($source) != 'application/pdf'):
return FALSE; // source is not a pdf file returns a failure
endif;
$sepa = '/'; // using '/' as file separation for nfs on linux.
$target = dirname($source) . $sepa . $target;
$size = intval($size); // only use as integer, default is 256
$page = intval($page); // only use as integer, default is 1
$page--; // default page 1, must be treated as 0 hereafter
if ($page < 0) {
$page = 0;
} // we cannot have negative values
//It breaks exactly right here
$img = new Imagick($source . "[$page]"); // [0] = first page, [1] = second page
$imH = $img->getImageHeight();
$imW = $img->getImageWidth();
if ($imH == 0) {
$imH = 1;
} // if the pdf page has no height use 1 instead
if ($imW == 0) {
$imW = 1;
} // if the pdf page has no width use 1 instead
$sizR = round($size * (min($imW, $imH) / max($imW, $imH))); // relative pixels of the shorter side
$img->setImageColorspace(255); // prevent image colors from inverting
$img->setImageBackgroundColor('white'); // set background color and flatten
$img = $img->flattenImages(); // prevents black zones on transparency in pdf
$img->setimageformat('jpeg');
if ($imH == $imW) {
$img->thumbnailimage($size, $size);
} // square page
if ($imH < $imW) {
$img->thumbnailimage($size, $sizR);
} // landscape page orientation
if ($imH > $imW) {
$img->thumbnailimage($sizR, $size);
} // portrait page orientation
if (!is_dir(dirname($target))) {
mkdir(dirname($target), 0777, true);
} // if not there make target directory
$img->writeimage($target);
$img->clear();
$img->destroy();
if (file_exists($target)) {
return $target;
} // return the path to the new file for further processing
endif;
return FALSE; // the source file was not available, or Imagick didn't create a file, so returns a failure
}
I thought that it was permission problems but found out that it's not.我以为是权限问题,但发现不是。
Update:更新:
If I initialize Imagick without parameters it won't throw errors and thus won't create thumbnail as it doesn't get file path.如果我在没有参数的情况下初始化Imagick ,它不会抛出错误,因此不会创建缩略图,因为它没有获取文件路径。 So, whenever I add file path and PHP starts searching for that file, and the error occurs.
因此,每当我添加文件路径并且 PHP 开始搜索该文件时,就会发生错误。 Inside the log, I noticed that the InvalidArgumentException exception was thrown by a Symfony framework.
在日志中,我注意到InvalidArgumentException异常是由Symfony框架引发的。
After debugging I found out that Imagick was not imported into the project.调试后我发现 Imagick 没有导入到项目中。 So, I just added
use Imagick
at the top of my Controller .所以,我只是在 Controller 的顶部添加了
use Imagick
Imagick 。
In my case i call $validator->fails()
two times.就我而言,我两次调用
$validator->fails()
。
In my case, the first call $validator->fails()
in my Controller action, after checking deleted the file.就我而言,在检查删除文件后,在我的 Controller 操作中第一次调用
$validator->fails()
。 The second call could not find this file.第二次调用找不到这个文件。
